What is adaR?

An R binding to the ada URL parser, now maintained by a research-software group.

adaR wraps the ada-url C++ library to give R a WHATWG-compliant URL parser with vectorised accessors, setters and clearers for every URL component. The latest release is a performance improvement to ada_url_parse. Maintenance moved from an individual to the gesistsa organisation, which also bumped the vendored parser.

What is collections?

A stable R data-structure package whose releases are now mostly compiler and checker upkeep.

collections provides queue, stack, deque, dict and ordered-dict types for R backed by C. The API has been settled since 0.3.x; recent releases are almost entirely maintenance against R's own tooling — an rchk memory-safety fix, then a modernization of the R/C interface. The one substantive change in the visible window is O(1) size() for queues and stacks.

adaR vs collections: editorial side-by-side

A
adaR
DEVOPS
0.0

An R binding to the ada URL parser, now maintained by a research-software group.

◆ Current state

adaR wraps the ada-url C++ library to give R a WHATWG-compliant URL parser with vectorised accessors, setters and clearers for every URL component. The latest release is a performance improvement to ada_url_parse. Maintenance moved from an individual to the gesistsa organisation, which also bumped the vendored parser.

◆ Where it's heading

The package reached feature completeness quickly — the accessor, setter and clearer families were all exported within months — and has since settled into tracking upstream ada-url and tuning parse speed. Note that this feed is backfilled out of order: the 0.1.0 initial release carries a later publication date than 0.3.0 and 0.3.1, so feed position does not reflect release sequence.

◆ Prediction

Expect continued ada-url version bumps and performance work; the API surface appears settled.

C0.0

A stable R data-structure package whose releases are now mostly compiler and checker upkeep.

◆ Current state

collections provides queue, stack, deque, dict and ordered-dict types for R backed by C. The API has been settled since 0.3.x; recent releases are almost entirely maintenance against R's own tooling — an rchk memory-safety fix, then a modernization of the R/C interface. The one substantive change in the visible window is O(1) size() for queues and stacks.

◆ Where it's heading

This is a finished package under custodial maintenance. The releases track pressure from outside the package — CRAN's rchk checks, R's evolving C API — rather than user-facing demand, and the issue-to-release pattern shows changes arriving one contributed pull request at a time.

◆ Prediction

Further releases will most likely be more R C-API conformance work as R continues restricting non-API entry points; nothing in the entries points at new data structures.
